UNetbootin won't boot

I'm trying to boot UNetbootin via USB on my netbook to recover files i got raped by a virus and windows crashed. When it comes to the boot screen it says Default or Help i go Default and it says Automatic boot in 10 seconds, counts down and then doesnt boot, just starts again from 10?

When i boot and use tab for "help" it has /ubnkern initrd=?ubninit file =/cdrom/preseed/ubuntu.seed boot = casper quiet splash

i checked on the USB and that file path is correct, accept the ubuntu.seed is 0kb so maybe that has something to do with it? not sure
